Memory systems and operation methods, electronic apparatuses

Abstract

An example memory system includes: a memory device and a memory controller. The memory device includes L memory dies, and memory blocks in different memory dies form a super block. The memory controller is configured to: determine first super blocks among super blocks, and the state parameters of first super blocks match the preset state parameters; determine M first read voltages based on first super blocks and first mapping tables; adjust the M first read voltages corresponding to the memory blocks of each first super block to M second read voltages; determine M first equilibrium read voltages based on the equilibrium values of second read voltages corresponding to memory blocks located in the same memory die in first super blocks; and update the first mapping table based on M first equilibrium voltage readings.
